FLfiSEING-VALVIE.

i hiallwlwm it mag concerns Be it known that I,,THoMAs: RLPAvN a citizenof the United States of America, re-

siding at Pittsburgh, in the county of Allegheny, State of Pennsylvania,have invented a certain newand useful'Improvement in Flushing-Valves, ofwhichthe following is afullgclear, and. exact description, referencebein'g had to the accompanyingdrawings, which form part of thisspecification;

This invention relatesto flushing devicesor valves fonflushing closetbowls,- lavatories, and other sanitary apparatus.

' The-device, taking the embodiment shown" in the accompanying drawings,o f my invention, relates more commonly 'to that type oi valve'in whichthe main valve which controls the source of supply is operated by thedifferential-pressure of the water, this' pres sure being'controlled bya secondary or relief "valve, and its primary object is to pro videasimple, durable, inexpensive and improved const-ruction therefor,whereby thereis provided a valve that is capable of causing asustaineduninterrupted flow of an abundant supply offlushing water,without such I impetus of delivery as occasions splattering .orsplashing within the bowl eratively manipulated 'by the depression andelevation of the closet-seat incident to use. As such a valve, itsobject is to provide mechanism which may. be easily manipulated withoutjarring and injurious ramming of the valve mechanism and whereby thevalve 7 may be returned without liability of canting or sticking; andvalve mechanism which is otherwise improved in detail ,of constructionas will be hereinafter more fully de-- scribed.

T. will now deseril'io my invention so that others skilled in the art towhich it appertains gnay understand and construct the same and, whilereference is had to the accompanying drawings in'connection with 'thisdescription, it. is to he understood that I do not desire to limit m-If;to the uni bodiniont of my iin ontionAlla'istraledin tlie drawingsitbeing prciriis d that the invention is \piihle of embo iment in variousv Spiification of Letters Patent. 1 Application filed my 28, 1911,Serial n0. s41,o 1a.

The particular typeof valve shown is of the class known as automaticallyoperating valves, that is, valves which are operated by the depressionand returning elevation of the closet seat, the depression of the seats'erving to place the valve mechanism, as stated above, in conditionpreparatory to flushing upon-removal of the prejsure from and consetiuent elevation of the seat, and in Figure show a side elevation of awater-closet having attached thereto a flushing valve of the typementioned, that is, of the-automatically operating type, and embodyingmy invention; Fig. 2 is an enlarged vertical sectiona-lview of the-valveshowingthe valve 1n the closed or normal position it occupies when theseat is inclined'or elevated; Fig. 3

is a similar view showing the position of the valve mechanismimmediatelyupon dc pressionof the closet seat; Fig. 4 is a similar view showing thevalvemechanism in fiushing position immediatelyafter release of thepressure upon the closet seat; and.Fig. 5 is a similar, but fragmentaryview showing modified form of valve of this-same automatically operatingtypeand to be herein after more fully referred to, in the body of thisspecification.-

The valve illustrated is the-type in which the fi ushing is effecteddirectly fromthesou'rce'of supply, that is ,.i' t is shown as having noauxiliary storage or flushing tank as is sometimes employed with valvesof this class and as such the source ofsupply is indicated bythenumeral2, leading into the inlet 3 of the casing 4. This inlet3 is formed bythe chamber 5 laterally commu nicating at- 6 with the chamber 'i' of thecasing 4.. Below the chamber 7 is the chamber 8 and leading therefrom,is the pa sageway 9, or discharge port-which cominunirates with thedischarge. pipe 10 leading to the closet bowl 11, or flushing rim 12 ofthe closet bowl or other apparatus to be flushed. The wall 12" whichseparates the clnunher 8 and passage' 9 from the chamber 7 c and chamberfx has the .Opening 13 in which is disposed the screw threaded removablebushing This bushing 14 carries .at' its top the valve seat 15 formedcoim'ilementary with the valve- 16 carried at the base of the piston l7.barrel-like member 18 having a suitable.

leathers andfdisks being clamped in position by the cap-piece23 havingscrew-threaded engagement with the top' clearly brought out. v 4

The" vfalve'16 has the-central bore 24 within which snugly fits thep'lug-lik'e stem 25 of the valve 26.. Thisplug 25 has the central inletpassage 27 leading to -the valve seat 28 which cooperates with the valve26 to nor-' mally close communication of the said passage 27 with thechamber 29 of the barrel '18. This passage-way 27 is form'ed to registerwith the passage-way. 27 of the valve 30, which is adapted to beelevatedas shown. in Fig. 3 into socketed engagement withthe bushing 14. Thiscommunication-of the pas-'- of the barrel 18 as sage-way 27 with that"of the passage 27 is effected by mounting of the'l'owerfend of the'stem'25 within the'upwardly extending cuplike' head 31 of the valve-30, and is maintained thereby'rat whatever relative operative positionthe-valve-may occupy. .This

head- 31 joarries a suitable stufling box 32.

The" pas'sa e 27" leads valve head 31, and the said bore34-coinmunieates with the-annular-f ooket 36 which carried by thestem37o .the'valveand. into which leads the passage-way 27f, no matterin what'position thesmall lateral or,' annular opening 38 of thepassage27 may 'l-ie .3vith respect to the entrance34. f

The stem 37 of the valve=30' rojects from. the casing 4 at the'lower'end tereof This part of the casing is preferab'ly'separatelyformed, being indicated by-the numeral 39, and screw-threaded to thedepending nippleportion 40 of thecasing proper. The upper.

pressure against the cap 23, the seat '28 is "carried upwardly intoclosing engagement with the valve 26 by an upward movement of the piston17 The upward movement of the. piston results in the upward travel orfurther opening of the valve 16,- in which position it remainspreparatory to the flushing operation which takes place immediatelyuponthe ,removal. of the pressure on the closet seat andconsequent return ofthe' valve stem 37'and its valve 30 to normal po-V mal position, ofcourse, as shown in Fig. 4, uncovers the .opening'within the bushing 14,bringing the chamber 7 and inlet chamber or passage 5 into direct andwide open com; mnnication with the lower chamber .8 and dischargepassage-way 9. This communication enables the water to pass from theinlet 2 to the chambers and passage-ways just mentioned to the dischargeport 10 and thence to the apparatus to be flushed while the valve 16remains open. During this-flow of water, the chamber 7 above the piston17 is being. filled from the source of supply through the openings 45,46 and 47, where it exerts its pressure upon the piston 17 of large areaagainst the slight resistance offered by the open lower portion of thechamber 7. The valve 16 preferably carries the head 16 which servestochoke off the water and proportionately increase the pressure exertedat the top of the piston as the valve, through such pressure, graduallygoes The opening 27 is preferably of a size that will prevent a too freedischarge of water from the top of the chamber 7.

In Fig. 5 I show a modified form of valve employing my invention,wherein the cap 23 just-ing scre\v 53 in lieu of the o ening '47 shownin the preceding views, and depending from the cap or top of the casing4%, is the wiper-rod 54-" which lies within the orifice 55 and serves,through the reciprocation of the piston 17 to keep the passageway 55free from dirt or deposits. which. would otherwise tend to clog it. Thecoiled spring, carriedwithin the barrel 18 of the piston 17. instead ofbearing against the under side of the cap 23, is interposed between theflange or shoulder of the valve 26 and the up or annular shoulthzr ofthe barrel 18, he upper portion of the valve stem tern'linati ng withinthe cap 23 and having the central here 57 intb which the lower end of;the \YlptW-lfltl 5i passes when the piston 17 is elevated. Theopcrationof this valve is the same as that described above with 1h:- ex-Qcplion that. \vatcl passes from the chamber of thearrel 18 of thepistoiifl'i'to the-top l of the chamber? through thcopcniug .Li of thescrew instead of the opening 4? i in the cap 23, as'showi in Fig. i. i

Further modifications in the structure shown'in the'accompanying tion.The valves, while of a design whichconduces to lightness andsymmetry,may be constructed in various diiferent ways wh ledrawingsmaybe made without departing fromrmy lnventhe general shape ofthe casing properand the disposition of the ports therein may also bevarled without sacrificing my invention.

The device is simple in constructionand the specific embodiment shown issuch that n the operation of the vallve,-the valve 30 as abovedescribed, is returned 'to its seat through the pressure of the spring44, althou h' it will be apparent that pressure is exerte upon theupperface of the valve 30 by the water in the chamber 7 However, thereturn of the valve 30 is, independent of the return of the valve 16to'its seat. This enables the valve 30 to immediately drop from thepassage 13 and thereby uncover a large mouth or entrance way to thepassage 9. preparatory to the slow, gradual closing of the valve 16 andresultant flow from the source of supply from the chamber 7 into thechamber 8 and thence tothe passage 9. i 1
